Currency Converter Web Application (ASP.NET / C#)

A simple web application that converts currency into US Dollars, Euros, and Japanese Yen. There is no submit, the conversion happens in real-time as the user types, the screen is also updated in real-time. The application input is a simple 3 textboxes, each for USD, EUR and JPY. When any data is entered into one of these boxes the other two immediately updated using AJAX. You will also be required to scrape a second web site to retrieve the current rate of exchange.

I just realized AJAX may not be needed, you would simply be doing client side calculations and updating using javascript.
